There are three ways to unlock a cell phone, you can purchase an unlock code from an online provider, buy an unlocking hardware device or unlock the phone yourself using a USB cable and software tools. Of the three ways, unlocking the phone yourself using a USB cable is one of the quickest and least expensive. You don't need to wait for someone else to send you unlock codes and it is a process that you can do yourself.
Find an online store that will sell you an unlocking software (see resource links). As of 2010 these programs cost between $20 to $50.
